To whom vtt may concern.-

Be it known that I, BENJAMINBRIscoaot' Detroit, in the county of Wayneand State-of Michigan, have invented a new and useful Hinged Seal-Lockfor RailwayfGar'Doors and I do declarethat the following is a true andaccurate description thereof',` reference being had to the accompanyingdrawing -and to'the :letters of reference?- marked thereon and being apartA 'ofthis specifica-A tion, in which-` Eigure l sealed and Figure 2is a similar view of thesam'e open and I unsealed.

Like letters indicate like parts in each 'gnl-e; l The nature of thisinvention relates to an improved-,i

method of ylocking the doors of railWay'eight-cars,

and of sealing the same when locked, so that, whenso sealed, the carcannot be entered byunauthoi'ized peisons without detection. Theinvention consists in the peculiarv construction and arrangement of twosemicircular segmentsof unequal diameters hinged together, the largerbeing provided with a a'ttened extension to 'pass through a slot in avlug at the adjacent end of the other, andper" `forated to receive .oneor more leaden rivets when closed afterlpassing through the staple-boltof the door, said rivets being headed by any convenient de-r vice andimpressed with any desired seal or Cypher.

In the drawing- A represents a cast or malleable nieta] semieircularsegment, having a lug, A', projecting outwardly from one end. 'The lugis slotted inthe direction: of the circumference of the segment.

'B is a similar but larger segment, hinged to the vother at d, andprovided-at its other end with aflattened extension, B', which passesthrough the slot re- Yferred to.

The extension is perforated with several. openings,
